WILLIAM HENRY BEACH, OF BRIDGENORTH, COUNTY OF SALOP, ENGLAND.

THERMO- CAUTER.

SPECIFICATION forming part of Letters Patent No. 420,672, dated February4, 1890. Application tiled October 23, 1889. Serial No. 327,909. (Nomodel.)

Be it known that 1, WILLIAM HENRY BEACH, veterinary surgeon, of 25 EastCastle Street, Bridgenorth, in the county of Salop, England, haveinvented new and useful Improvements in Thermo-Cauters, of which thefollowing is a full, clear, and exact description.

This invention relates to a portable receiver for use in connection withDr. Paquelins well-known thermo-cauter, the purpose of the receiverbeing to contain and retain the volatile liquid while permitting thecarrying off of its vapor, in order to maintain the cauter at its properstate of incandescence.

The invention has special reference to that form of the Paquelinthermo-cauter in which a bottle is provided for containing thebenzoline, which bottle it has been usual to suspend from thebutton-hole of the operators coat, the bottle being connected byflexible tubes with the pneumatic bulb on the one hand and with thethermo-cauteron the other.

The thermo-cauter is used both for human surgery'and in veterinarypractice, and in the latter case this means of holding the store ofbenzoline is apt to lead to dangerous accident-s, as, owing to a suddenmovement of the operator, in order to escape injury by the animal undertreatment or from other cause, the bottle is liable to be broken.Moreover, the movements of the operator 'are cramped, as, should heassume a stooping position, the bottle is apt, to be inverted. Thebenzoline is consequently liable to choke the outlet-tube leading to thecauter, extinguish the latter, and escape in the liquid state from theinstrument.

The object of my invention is to provide a reservoir which forms anintegral part of the cauter itself, and which may be held in anyposition without causing the grave objections above referred to.

Reference is to be had to the accompanying drawing, forming part of thisspecification, wherein I have represented a central longitudinal sectionof my improved reserthe cylinder.

E is the Paquelin thermo-cauter, which, being well known, needs nodescription It is connected by a screw-joint with a metal cap F, whichis connected with the closed end of the cylinder A only through theintervention of a block G of ebony or other poor conductor of heat. Theouter tube D communicates with an orifice through said block and withthe bore of the screw-nozzle of the cap F, to which the cauter isscrewed.

The receptacle A thus constitutes the handle of the cauter, and isfilled to so much less than half its capacity that the benzoline cannotrun out of the tubes 0 D in whatever position it may be held. Thescrewcap B is provided with a nozzle for the attachment of a flexibletube by which the inlet-tube C is connected with the pneumatic 7- bulbH. Screw-plugs (not shown) are provided for closing the inlet and outletorifices in the capsB F when the air-pipe and cauter are disconnectedfrom the reservoir for transport.

Having now particularly described and ascertained the nature of the saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is 1. The combination, with a therrno-cauter, of acylindrical reservoir for volatile liquid, said reservoir having inletand outlet tubes projecting axially within it from opposite ends andrespectively in connection with the pneumatic bulb and with the cauter,said reservoir forming the handle for the thermoc-auter, substantiallyas specified.

2. The combination, with a thermocauter, of a cylindrical reservoir forvolatile liquids,

said reservoir having air-inlet and air and vapor outlet tubesprojecting axially within it from opposite ends and terminating within ashort distance from each other, the said reservoir serving as the handlefor the canter and being connected thereto through a non-conductingblock, substantially as specified.

The foregoing specification of my improvements in therlno-cauters signedby me this 10 10th day of September, 1889.
